Description

Technical Field

[0001] This invention relates to the field of electrocoagulation tweezers technology, specifically a bipolar electrocoagulation tweezers with an inner anti-adhesion side and an outer insulation side. Background Technology

[0002] Bipolar electrocoagulation forceps serve multiple purposes in surgical procedures, primarily including hemostasis, minimizing tissue damage, and providing a safer surgical environment. Due to their low current, low heat generation, and minimal tissue damage, bipolar electrocoagulation forceps are widely used in surgery. Their working principle involves the tip of the forceps simultaneously contacting both ends of an electrified tissue. The high temperature generated by the current causes the tissue to coagulate instantly, achieving hemostasis.

[0003] Existing bipolar electrocoagulation forceps are difficult to effectively isolate surrounding human tissue during actual operation. The insulation effect on the outer side of the bipolar electrocoagulation forceps is poor, and the heating can easily injure surrounding tissues, causing irreversible damage to the patient. Furthermore, during the process of hemostasis by generating high temperature with current, tissue coagulation can easily adhere to the inner side of the bipolar electrocoagulation forceps, increasing the risk of blood vessel re-rupture when the forceps are opened. The bipolar electrocoagulation forceps are also not easy to achieve efficient separation from tissue when opened, which is not conducive to human use. Therefore, those skilled in the art have provided a bipolar electrocoagulation forceps with anti-adhesion on the inner side and insulation on the outer side to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to provide a bipolar electrocoagulation forceps with an inner anti-adhesion side and an outer insulation side, in order to solve the problems that existing bipolar electrocoagulation forceps are difficult to effectively block surrounding human tissue during actual operation, the outer side of the heated bipolar electrocoagulation forceps is prone to accidentally injuring surrounding human tissue, and when using high temperature generated by current for hemostasis, the tissue coagulation is prone to sticking to the inner side of the bipolar electrocoagulation forceps, which will increase the risk of blood vessel re-rupture when the bipolar electrocoagulation forceps are opened.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bipolar electrocoagulation forceps with an inner anti-adhesion side and an outer insulation side, comprising:

[0006] The forceps body is provided in two symmetrical sets, with the rear ends of both sets of forceps body fixedly mounted on the electrode holder, and the front ends of both sets of forceps body provided with forceps tips for conducting electricity.

[0007] Two sets of insulating baffles are symmetrically arranged on the left and right sides, and the two sets of insulating baffles are located on the outside of the two sets of tweezers. The rear ends of the two sets of insulating baffles are fixedly installed on the electrode fixing base. A limiting component is installed between the insulating baffles and the electrode fixing base. The limiting component is used to limit the movement range of the insulating baffles. A squeezing component is provided on the outside of the tweezers for controlling its movement. The squeezing component can drive the insulating baffles to move to a limited position through the limiting component.

[0008] An insulating scraper ring is disposed at the front end of the tweezer tip. A push-pull assembly is installed between the insulating scraper ring and the insulating stop strip. The push-pull assembly is used to control the insulating scraper ring to slide radially along the outer ring of the tweezer tip when relative movement occurs between the insulating stop strip and the tweezer body.

[0009] Preferably, the limiting component includes a support block fixedly installed on the side of the electrode fixing seat and a support plate fixedly installed on the side of the insulating baffle. A sliding bracket connected to the extrusion component is slidably installed inside the support plate. The top and bottom of the support block are both connected to the sliding bracket via a hinged first connecting rod.

[0010] Preferably, the sliding bracket includes two sets of upper and lower sliding rods that slide through the support plate. A baffle is fixedly installed at one end of each set of sliding rods. Two sets of first springs sleeved on the outer ring of the sliding rods are installed between the baffle and the support plate. A connecting block is fixedly installed at the other end of each set of sliding rods. A push rod that is slidably connected to the extrusion assembly is fixedly installed at the top and bottom of the connecting block. The push rod is rotatably connected to the end of the first connecting rod.

[0011] Preferably, the extrusion assembly includes an extrusion frame fixedly installed on the side of the tweezers body, the insulating baffle movably passes through the extrusion frame, and the top and bottom of the extrusion frame are provided with a first sliding groove and a second sliding groove for the push rod to slide, and the first sliding groove and the second sliding groove are connected.

[0012] The push rod slides within the first groove to allow the tweezers and the insulating strip to move synchronously, and the push rod slides within the second groove to allow relative movement between the tweezers and the insulating strip.

[0013] Preferably, the side of the squeezing frame away from the tweezers has multiple sets of equidistant anti-slip grooves.

[0014] Preferably, multiple sets of second springs are fixedly installed between the side of the insulating baffle away from the tweezers and the inner wall of the squeezing frame, and multiple sets of limiting rods that move through the second springs are fixedly installed between the squeezing frame and the tweezers.

[0017] Preferably, both the tweezers and the insulating strip are made of stainless steel with an external insulating coating.

[0018] Preferably, the tweezers tip is made of silver-nickel alloy.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] When using the compression assembly to control the forceps body and its tip for surgical operations, the insulating strips on both sides of the bipolar electrocoagulation forceps can move to a fixed position along with the forceps body. These insulating strips create a certain operating space during surgical operations, providing good insulation and heat protection for both sides of the forceps. This prevents tissue on the outside of the forceps from adhering to the heated tip, thus improving the safety of the actual surgical procedure. The limiting assembly facilitates the repositioning of the insulating strips and restricts their range of motion. Simultaneously, the insulating scraping rings at the tips of the two forceps slide around the outer ring of the tip when the forceps body and insulating strips move relative to each other. These rings quickly separate the tissue from the tip after the surgical operation, effectively preventing adhesion between the inside of the forceps and the tissue, reducing the risk of blood vessel re-rupture when the forceps are opened, and further enhancing the safety of the bipolar electrocoagulation forceps in actual use.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 8 In this embodiment of the invention, a bipolar electrocoagulation forceps with internal anti-adhesion and external insulation includes two sets of forceps bodies 10 and insulating strips 13 symmetrically arranged on the left and right. The rear ends of both sets of forceps bodies 10 are fixedly installed on the electrode fixing base 11, and the front ends of both sets of forceps bodies 10 are provided with forceps tips 12 for conducting electricity. The two sets of insulating strips 13 are located outside the two sets of forceps bodies 10, and the rear ends of both sets of insulating strips 13 are fixedly installed on the electrode fixing base 11. A limiting component 20 is installed between the insulating strips 13 and the electrode fixing base 11. The limiting component 20 is used to limit the movement range of the insulating strips 13. A squeezing component 30 is provided on the outside of the forceps body 10 for controlling its movement. The squeezing component 30 can drive the insulating strips 13 to move to a limited position through the limiting component 20.

[0036] The working principle of bipolar electrocoagulation forceps is to generate a thermal effect between the two ends of the forceps body 10 through high-frequency current, which coagulates tissue proteins and achieves hemostasis. Its characteristic is that the current is transmitted only between the forceps tips 12, which causes less damage to the surrounding tissue and has a high safety. When using bipolar electrocoagulation forceps for surgery, the doctor needs to fully insert the forceps tips 12 into the tissue to ensure that the current generates a thermal effect in the tissue. During operation, care should be taken to control the current intensity to avoid unnecessary damage to the tissue. After the operation, the forceps need to be cleaned and disinfected for the next use.

[0037] In actual use, the electrode holder 11 is electrically connected to the external control device via a cable at the rear end. The operator holds the squeezing components 30 on both sides of the bipolar electrocoagulation forceps. When the squeezing components 30 drive the two sets of forceps bodies 10 and the forceps tips 12 at their ends to move relative to each other, the squeezing components 30 can drive the insulating baffles 13 to move through the limiting components 20. When the squeezing components 30 drive the insulating baffles 13 to the limited position, the insulating baffles 13 are tightened and positioned by the limiting components 20. At this time, the squeezing components 30 can drive the forceps bodies 10 to continue moving, which can squeeze the two sets of forceps tips 12 to the tissue that needs hemostasis. The forceps tips 12 at the ends of the two sets of forceps bodies 10 clamp the tissue for heating and hemostasis. When using bipolar electrocoagulation forceps for surgery, the surrounding operating environment is relatively complex. The two sets of insulating baffles 13 on the outside of the bipolar electrocoagulation forceps can isolate a certain operating space for the forceps tips 12, thereby effectively avoiding damage to the surrounding tissue by the forceps tips 12 during heating and hemostasis.

[0038] The bipolar electrocoagulation forceps, which are internally anti-adhesive and externally insulated, also include an insulating scraper ring 14 located at the front end of the forceps tip 12. A push-pull assembly 40 is installed between the insulating scraper ring 14 and the insulating stop strip 13. The push-pull assembly 40 is used to control the insulating scraper ring 14 to slide radially along the outer ring of the forceps tip 12 when relative movement occurs between the insulating stop strip 13 and the forceps body 10. When the insulating stop strip 13 moves with the squeezing assembly 30 to the position where the limiting position assembly 20 is tightened, the squeezing assembly 30 drives the forceps body 10 to continue moving, which can drive the insulating scraper ring 14 through the push-pull assembly 40. When the ring 14 is displaced and the forceps tip 12 moves away from the insulating barrier 13, the two sets of forceps tips 12 approach each other to heat and stop bleeding in the tissue. At this time, the insulating scraping ring 14 is pulled by the push-pull assembly 40 to move to the end close to the forceps body 10. After the operation, when the bipolar electrocoagulation forceps are repositioned and opened, the insulating scraping ring 14 is pulled by the push-pull assembly 40 from the rear end of the forceps tip 12 to its front end. The insulating scraping ring 14 can easily and quickly separate the tissue from the forceps tip 12, thereby effectively avoiding the forceps tip 12 from adhering to the tissue and causing rebleeding.

[0039] In one embodiment, see Figures 1 to 7Specifically, the limiting component 20 includes a support block 201 fixedly installed on the side of the electrode fixing seat 11 and a support plate 202 fixedly installed on the side of the insulating baffle 13. A sliding bracket 203 connected to the extrusion component 30 is slidably installed inside the support plate 202. The top and bottom of the support block 201 are connected to the sliding bracket 203 through a hinged first connecting rod 204. Correspondingly, the sliding bracket 203 includes two sets of upper and lower sliding rods 2031 that slide through the support plate 202. A baffle 2032 is fixedly installed at one end of the two sets of sliding rods 2031. Two sets of first springs 2033 are installed between the baffle 2032 and the support plate 202 and are sleeved on the outer ring of the sliding rods 2031. A connecting block 2034 is fixedly installed at the other end of the two sets of sliding rods 2031. A push rod 2035 that is slidably connected to the extrusion component 30 is fixedly installed at the top and bottom of the connecting block 2034. The push rod 2035 is rotatably connected to the end of the first connecting rod 204.

[0040] When the squeezing assembly 30 drives the tweezers body 10 to start moving, the squeezing assembly 30 can synchronously drive the connecting block 2034 to move via the push rod 2035. The connecting block 2034 can push the support plate 202 and the insulating baffle 13 to move synchronously with the tweezers body 10 via the sliding rod 2031 connected to it. During the movement of the insulating baffle 13, the connecting block 2034 and the push rod 2035 can be pulled by the first connecting rod 204 to drive the sliding rod 2031 to slide inside the support plate 202. When the first connecting rod 204 pulls the connecting block 2034 to move to When the insulating baffle 13 abuts against the support plate 202, it moves to a fixed position. The squeezing assembly 30 can drive the forceps body 10 to continue moving. The insulating baffle 13 provides a safe operating space for the surgical operation of the forceps tip 12 at the fixed position. When the slide bar 2031 moves, it can simultaneously drive the baffle 2032 to move. The baffle 2032 can provide a movement limit for the movement of the slide bar 2031. The baffle 2032 can drive the first spring 2033 to extend and retract. The first spring 2033 facilitates the subsequent automatic reset of the insulating baffle 13.

[0041] Based on the above embodiments, in detail, the squeezing assembly 30 includes a squeezing frame 301 fixedly installed on the side of the tweezers body 10, and an insulating baffle 13 movably passes through the squeezing frame 301. The top and bottom of the squeezing frame 301 are provided with a first sliding groove 302 and a second sliding groove 303 for the push rod 2035 to slide, and the first sliding groove 302 and the second sliding groove 303 are connected. The push rod 2035 slides in the first sliding groove 302 to make the tweezers body 10 and the insulating baffle 13 move synchronously, and the push rod 2035 slides in the second sliding groove 303 to make relative movement between the tweezers body 10 and the insulating baffle 13.

[0042] The squeezing frame 301 on the outer side of the forceps body 10 improves the convenience of using bipolar electrocoagulation forceps by medical staff. When the forceps body 10 is moved by the squeezing frame 301, the forceps body 10 drives the connecting block 2034 through the push rod 2035 slidably connected inside the first slide groove 302. When the push rod 2035 slides inside the first slide groove 302, the insulating stop 13 can move along with the forceps body 10. When the insulating stop 13 moves to the position limited by the limiting component 20, the push rod 2035 moves into the inside of the second slide groove 303. The squeezing frame 301 continues to push the forceps body 10 to move. The second slide groove 303 can provide corresponding accommodating space for the positioning of the push rod 2035. The side of the squeezing frame 301 away from the forceps body 10 has multiple sets of equidistant anti-slip grooves 15, which can help medical staff to firmly hold the bipolar electrocoagulation forceps with anti-adhesion on the inner side and insulation on the outer side when performing surgical operations.

[0043] Furthermore, multiple sets of second springs 16 are fixedly installed between the side of the insulating baffle 13 away from the forceps body 10 and the inner wall of the compression frame 301. Multiple sets of limiting rods 17 that move through the second springs 16 are fixedly installed between the compression frame 301 and the forceps body 10. A through hole 18 is provided in the insulating baffle 13 for the limiting rods 17 to move. When relative movement occurs between the insulating baffle 13 and the forceps body 10, the compression frame 301 can drive the limiting rods 17 and the second springs 16 to extend and retract. The second springs 16 can provide a good auxiliary effect for the subsequent reset of the compression frame 301 and the forceps body 10, and the limiting rods 17 can prevent the second springs 16 from lateral deformation, thereby improving the actual service life of the bipolar electrocoagulation forceps.

[0044] In one embodiment, see Figures 1-5 and Figure 8 Specifically, the push-pull assembly 40 includes a fixing block 401 fixedly installed inside the insulating baffle 13. The top and bottom of the fixing block 401 are connected to the insulating scraper ring 14 via a hinged second connecting rod 402. Multiple sets of support rods 403 located outside the tweezer tip 12 are fixedly installed on the insulating scraper ring 14. The ends of the multiple sets of support rods 403 slide into the interior of the tweezer body 10.

[0045] After the insulating baffle 13 moves to the fixed position, the forceps body 10 continues to move, which can drive the support rod 403 and the insulating scraping ring 14 at its end to move. The insulating scraping ring 14 is pulled and limited by the second connecting rod 402, and can move along the axial direction of the forceps tip 12 during the process of moving with the forceps body 10. The insulating scraping ring 14 drives multiple sets of support rods 403 to slide inside the forceps body 10. The support rods 403 can provide stable moving support for the insulating scraping ring 14. When the two sets of forceps tips 12 move close to each other, the tissue is heated to stop bleeding. At this time, the insulating scraping ring 14 moves close to the end of the forceps body 10. When the forceps tip 12 is finished, it opens. The insulating scraping ring 14 is pushed by the second connecting rod 402 to move towards the front end of the forceps tip 12. The movement of the insulating scraping ring 14 on the outer ring of the forceps tip 12 can effectively prevent adhesion from occurring on the inner side of the bipolar electrocoagulation forceps.

[0046] The existing bipolar electrocoagulation forceps are equipped with water outlet holes 19 for delivering physiological saline to reduce tissue adhesion. This allows for rapid cooling of the forceps tip 12 after use. The bipolar electrocoagulation forceps, which are internally anti-adhesion and externally insulated, have multiple sets of water outlet holes 19 located inside the forceps tip 12 at the front end of the forceps body 10. The water outlet holes 19 are connected to an external device for delivering physiological saline. The components of the device for delivering physiological saline are all existing technologies and will not be described in detail here. After the bipolar electrocoagulation forceps are used, physiological saline is delivered to the forceps tip 12 through the water outlet holes 19 for cooling, which facilitates rapid cooling of the tissue and components, thereby further reducing the possibility of tissue adhesion after the use of the bipolar electrocoagulation forceps.

[0047] Both the forceps body 10 and the insulating strip 13 are made of stainless steel with an external insulating coating. The forceps body 10 and the insulating strip 13 can be made of stainless steel, such as 304 medical steel. The above materials have high hardness, are not easily deformed, and are suitable for long-term use. The insulating coating on the stainless steel can be made of polytetrafluoroethylene (PTFE). PTFE is heat resistant (above 260℃), has excellent insulation, and a low coefficient of friction. During the processing of the tool, the insulating material can be encapsulated in the metal instrument body through precision injection molding. After the insulating coating is cured on the component at high temperature, it can effectively ensure that there are no bubbles, no gaps, and prevent current leakage. The insulating scraper ring 14 can be made of materials with good insulation and heat insulation properties, such as composite materials, ceramic materials, and high-performance polymer materials. The tip 12 of the bipolar electrocoagulation forceps can be made of common metal materials with a non-adhesive coating. The non-adhesive coating can be a Teflon coating. The Teflon coating can reduce the adhesion between the tissue and the surface of the forceps teeth, thereby effectively reducing tissue adhesion during repeated use.

[0048] Working principle: The operator moves the forceps 10 by squeezing the frame 301. When the two sets of forceps 10 move relative to each other, the squeezing frame 301 can move the push rod 2035 and the connecting block 2034 through the first sliding groove 302 inside it. The connecting block 2034 can move the insulating baffle 13 and the forceps 10 synchronously through the sliding rod 2031 and the support plate 202. When the insulating baffle 13 moves with the forceps 10 to the position restricted by the connecting block 2034 and the first connecting rod 204, the insulating baffle 13 on the outside of the bipolar electrocoagulation forceps can separate a certain operating space for the surgical operation of the forceps tip 12. The push rod 2035 moves to the inside of the second sliding groove 303. The squeezing frame 301 can continue to move the forceps 10. The displacement of the forceps 10 relative to the insulating baffle 13 can drive the insulating scraping ring 14 to slide on the outer ring of the forceps tip 12.

[0049] When the forceps body 10 moves away from the insulating baffle 13, the insulating scraping ring 14 is pulled by the second connecting rod 402 and moves radially from the front end to the rear end of the forceps tip 12. When the two sets of forceps tips 12 approach to heat the tissue, the insulating scraping ring 14 is located near the front end of the forceps body 10 at the water outlet 19. After the forceps tip 12 stops bleeding, the saline solution output from the water outlet 19 can flow to the insulating scraping ring 14 and the forceps tip 12. When the two sets of forceps body 10 open and reset, the insulating scraping ring 14 can move towards the front end of the forceps tip 12. The insulating scraping ring 14 can effectively prevent the tissue from sticking to the forceps tip 12. At the same time, the first spring 2033 and the second spring 16 and other components can assist the stable reset of the forceps body 10 and the insulating baffle 13.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
